Are Johnson Brothers products safe for modern use?

Many Johnson Brothers products remain safe for modern use, though care is needed with older pieces. Items made before the 1970s may contain glazes with materials no longer used today. These pieces are often better suited for display rather than food use. Later production followed updated standards, making them more suitable for everyday use. Dishwashers and microwaves may affect older ware, especially decorated surfaces. Collectors often prefer gentle hand washing to preserve designs. Checking backstamps and production dates can help determine suitability for use.
